In this paper, the mechanical properties of polyvinyl chloride (PVC)-coated woven fabric at high-temperature and after exposure to high-temperature were studied using a uniaxial tensile test. The test temperature range is 20 °C to 170 °C. The high-temperature test shows that the maximum stress at 170 °C reduced to 57%−59% of that at 20 °C. The after exposure to high-temperature test of prestressing shows that the combined effect of high-temperature and constant external force enhanced the stiffness and reduced the material’s impact toughness. The experimental phenomena can be explained by polymer physics.

四种类型的PVC涂层机织物在高温和高温下的机械性能

本文采用单轴拉伸试验研究了聚氯乙烯（PVC）涂层机织织物在高温下和暴露于高温后的力学性能。测试温度范围是20°C至170°C。高温测试表明，170°C时的最大应力降低到20°C时的57％-59％。经过预应力高温测试后，发现高温和恒定外力的共同作用增强了刚度，降低了材料的冲击韧性。实验现象可以用高分子物理学来解释。
